AIXTRON SE successfully placed EUR 450 million convertible bonds

Herzogenrath, April 15, 2026 – AIXTRON SE (the “Company”) (FSE: AIXA, ISIN DE000A0WMPJ6) placed today unsecured and unsubordinated convertible bonds in an aggregate principal amount of EUR 450 million due April 2031, ISIN: DE000A460HP9 (the “Bonds”). The shareholders’ pre-emptive right (Bezugsrecht) was excluded.

The Bonds, with an aggregated principal amount of EUR 450 million and a denomination of EUR 100,000 per Bond, will be issued by AIXTRON SE. The Bonds will be convertible into new and/or existing ordinary registered shares of the Company with no par value (the "Shares") representing approx. 7.9% of the Company’s share capital.

The Bonds will be issued at 100% of their principal amount. Unless previously converted, repaid or repurchased and cancelled, the Bonds will be redeemed at maturity on 23 April 2031 at their accreted redemption amount, equal to 101.26% of their principal amount (the “Accreted Redemption Amount”). The initial conversion price of EUR 50.375, corresponds to a conversion premium of 30% above the reference share price of EUR 38.75, set as the clearing price of the ordinary registered share in the concurrent offering of existing shares as described below. In light of the Accreted Redemption Amount, the effective conversion price of the Bonds is approx. EUR 51.010 at maturity. The Bonds will bear no periodic interest.

The settlement of the Bonds is expected to take place on or around 23 April 2026 (the "Issue Date"). The Company intends to apply for inclusion of the Bonds to trading on the Open Market (Freiverkehr) segment of the Frankfurt Stock Exchange no later than 3 months after the Issue Date.

The net proceeds of the offering will be used for general corporate purposes, which may include investments to support organic growth, acquisitions and share buybacks.

The Company has agreed to a lock-up period from pricing of the Offering to 90 days after the Issue Date, which is subject to certain customary exceptions and waiver by the Joint Global Coordinators.

In addition, a simultaneous placement of existing shares of the Company has been conducted on behalf of certain subscribers of the Bonds who wished to sell such shares in short sales to hedge the market risk of an investment in the Bonds at a placement price determined by way of an accelerated bookbuilding process. The Company will not receive any proceeds from this simultaneous offering of existing shares.

This announcement and the offer when made, in member states of the EEA (each a "Member State") and the United Kingdom ("UK") are only addressed to and directed at persons who are "qualified investors" as defined in the Prospectus Regulation or the Public Offers and Admissions to Trading Regulations 2024 ("POATRs") ("Qualified Investors"). Each person in a Member State or in the UK who initially acquires any Bonds or to whom any offer of Bonds may be made and, to the extent applicable, any funds on behalf of which such person is acquiring the Bonds that are located in a Member State or in the UK will be deemed to have represented, acknowledged and agreed that it is a Qualified Investor.

In addition, in the UK, this announcement is only being distributed to and is only directed at (i) persons who have professional experience in matters relating to investments falling within Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005, as amended (the "Order"), (ii) high net worth entities falling withing Article 49(2) of the Order and (iii) persons at or to whom it can otherwise lawfully be distributed or directed (all such persons together being referred to as "relevant persons"). The securities are only available to, and any invitation, offer or agreement to subscribe, purchase or otherwise acquire such securities will be engaged in only with, relevant persons. Any person who is not a relevant person should not act or rely on this notification or any of its contents.

MIFID II: Solely for the purposes of the EEA manufacturer's product approval process, contained within: (a) EU Directive 2014/65/EU on markets in financial instruments, as amended ("MiFID II"); (b) Articles 9 and 10 of commission delegated directive (EU) 2017/593 supplementing MiFID II; and (c) local implementing measures (together, the "MiFID II Product Governance Requirements"), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" (for the purposes of the MiFID II Product Governance Requirements) may otherwise have with respect thereto, the target market assessment in respect of the Bonds has led to the conclusion that: (i) the target market for the Bonds is eligible counterparties and professional clients only, each as defined in MiFID II; and (ii) all channels for distribution of the Bonds to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling or recommending the Bonds (a "distributor") should take into consideration the manufacturer's target market assessment; however, a distributor subject to MiFID II is responsible for undertaking its own target market assessment in respect of the Bonds (by either adopting or refining the manufacturer's target market assessment) and determining appropriate distribution channels.

The target market assessment is without prejudice to the requirements of any contractual or legal selling restrictions in relation to any offering of the securities. For the avoidance of doubt, the target market assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of MiFID II; or (b) a recommendation to any investor or group of investors to invest in, or purchase, or take any action whatsoever with respect to the Bonds.

UK MIFIR: Solely for the purposes of the UK manufacturer's product approval process, the target market assessment in respect of the Bonds has led to the conclusion that: (i) the target market for the Bonds is only eligible counterparties, as defined in the FCA Handbook Conduct of Business Sourcebook ("COBS"), and professional clients, as defined in Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 ("UK MiFIR"); and (ii) all channels for distribution of the Bonds to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling or recommending the Bonds (a "distributor") should take into consideration the manufacturer's target market assessment; however, a distributor subject to the FCA Handbook Product Intervention and Product Governance Sourcebook (the "UK MiFIR Product Governance Rules") is responsible for undertaking its own target market assessment in respect of the Bonds (by either adopting or refining the manufacturer's target market assessment) and determining appropriate distribution channels.

The target market assessment is without prejudice to the requirements of any contractual or legal selling restrictions in relation to any offering of the securities. For the avoidance of doubt, the target market assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of UK MiFIR; or (b) a recommendation to any investor or group of investors to invest in, or purchase, or take any action whatsoever with respect to the Bonds.

The Bonds are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the EEA. For these purposes, a "retail investor" means (a) a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of MiFID II; (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended, the "Insurance Distribution Directive"), where that customer would not qualify as a professional client as defined in point (10) of article 4(1) of MiFID II. Consequently, no key information document required by Regulation (EU) No 1286/2014 (the "EU PRIIPs Regulation") for offering or selling the Bonds or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the Bonds or otherwise making them available to any retail investor in the EEA may be unlawful under the EU PRIIPs Regulation.

The Bonds are not intended to be offered, sold, distributed or otherwise made available to and should not be offered, sold, distributed or otherwise made available to any retail investor in the UK. For these purposes, a retail investor means a person who is not a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 (the "EUWA"). Consequently, no disclosure document required by the FCA Product Disclosure Sourcebook (“DISC”) for offering, selling or distributing the Bonds or otherwise making them available to retail investors in the UK has been prepared and therefore offering, selling or distributing the Bonds or otherwise making them available to any retail investor in the UK may be unlawful under DISC and the Consumer Composite Investments (Designated Activities) Regulations 2024.

No action has been taken that would permit an offering or an acquisition of, or a solicitation of an offer to purchase, sell or subscribe for, the securities or a distribution of this announcement in any jurisdiction where such action would be unlawful. Persons into whose possession this announcement comes are required to inform themselves about and to observe any such restrictions.

This announcement does not constitute a recommendation or advice concerning the placement of, or invitation to submit any offer to purchase, sell or subscribe for, any securities. Investors should consult a professional advisor as to the suitability of the placement of, or invitation to submit any offer to purchase, sell or subscribe for, any securities for the person concerned.
